Abstract

ABSTRACT

Ionizing radiation offers great benefit to people in the hospital through diagnostic and therapeutic procedures to patients but undue radiation may create short- and long-term problems for medical staff & public. The goal of the study is to monitor the real-time radiation inside & outside of the three large hospital campuses in Dhaka city of Bangladesh namely the National Institute of Cancer Research & Hospital (NICRH), National Heart Foundation Hospital & Research Institute (NHFH), Kidney Foundation Hospital & Research Institute (KFH) and estimation of radiological risk on medical staff& public. The average real-time radiation dose rate & calculated average twelve-monthly effective doses to medical staff and public arising from the NICRH, NHFH, KFH were found to be1.781 ± 0.310 μSv/h, 1.685 ± 0.307μSv/h, 1.735 ± 0.341μSv/hand 3.111 ± 0.556mSv, 2.952 ± 0.437 mSv, 3.039 ± 0.329 mSv respectively. The excess life-time cancer risk (ELCR) on medical staff & public was estimated based on the twelve-monthly effective dose and varied from 8.972 Χ 10-3 to 18.938 Χ 10-3with average of 12.071 Χ 10-3. The average twelve-monthly effective dose and ELCR on medical staff were lower than those of the permissible limit. Real-time radiation monitoring inside & outside of the large hospital campuses is essential for detecting a malfunction of the radiation generating equipment and incorrect handling of the radioactive substances. The study would assist in minimizing radiological risk to medical staff & public and thereby would ensure the environment in the hospital is free from radioactive contamination.
